Design Notes

Place the sense resistor close to the AD8212S inputs to minimize parasitic inductance and resistance. Use Kelvin connections to the shunt to ensure accurate voltage sensing. Keep the input traces short and shielded from noisy power traces to maintain high common-mode rejection.

The AD8212S operates from a 5 V supply. Ensure the supply is well decoupled with a 0.1 uF ceramic capacitor placed close to the VS pin. The supply current is low, but proper decoupling prevents noise from affecting the measurement accuracy.

When using an external PNP transistor to extend the common-mode voltage beyond 65 V, ensure the transistor's breakdown voltage exceeds the maximum common-mode voltage. Also, verify that the transistor's base current does not affect the measurement accuracy. Refer to the datasheet for the recommended transistor configuration.
